What is the significance of substrate specificity in enzymes and how does it vary among different enzymes?
Substrate specificity is the ability of an enzyme to discriminate between similar molecules. Reaction specificity is usually absolute, but the degree of substrate specificity may vary among different enzymes.
Explain the role of enzymes in the body and their function as protein catalysts.
Enzymes are protein catalysts that increase the rate of reactions without being changed in the overall process. They selectively channel reactants into useful pathways and direct all metabolic events.
Describe the nomenclature system used for assigning names to enzymes.
Each enzyme is assigned a recommended name, commonly with the suffix “-ase” attached to the substrate of the reaction or to a description of the action performed. Enzymes also have systematic names based on a naming system divided into six major classes, each with numerous subgroups.
Give an example of an enzyme with a recommended name and explain the naming convention used.
An example of an enzyme with a recommended name is 'glucosidase', where the suffix “-ase” is attached to the substrate of the reaction. This naming convention is commonly used for most enzymes.
Test your knowledge about enzymes and their role as protein catalysts in biological reactions. Learn how enzymes selectively channel substrates into useful pathways in the body.
